Improve require speed

I tested this by creating a new project and adding just time-require and chalk. I then created a simple time.js file with the following contents:

require('time-require')
require('chalk')

Results for Chalk 1.x (1.1.3 as of this posting):

I ran the tests several times locally and the results were all within 1ms each time.

For long running processes, the difference here is obviously negligible so I’ll understand if this gets closed out.

That being said, for CLI utils where boot time and responsiveness are far more important, it’s unfortunate that just using 2.x adds an additional 5ms+ on average that you can’t get back.

Not sure what you suggest we do about this.

The community complains about many tiny modules, and then gets mad when X module doesn’t have all of these features out of the box. So we’ve struck a somewhat bearable middleground by thinking really hard about every dependency we include.
